Hi again,
I decided to look through the /proc/iomem pseudo-file to see if the mapping
looked reasonable. I believe the kernel may be corrupted since there is
garbage in the map for the usb:
ubuntu@arm-hf:~$ cat /proc/iomem
44e07000-44e07fff : /ocp/gpio@44e07000
44e07000-44e07fff : 44e07000.gpio
44e09000-44e0afff : /ocp/serial@44e09000
44e09000-44e0afff : omap_uart
44e0b000-44e0bfff : /ocp/i2c@44e0b000
44e0b000-44e0bfff : /ocp/i2c@44e0b000
??@ ??F ? e10623 : @
44e10628-44e1062b : /ocp/usb@47400000
44e10800-44e10a37 : /pinmux@44e10800
44e10800-44e10a37 : pinctrl-single
...
On Angstrom (where everything is working) I see:
root@beaglebone:/proc# more iomem
44e07000-44e07fff : /ocp/gpio@44e07000
44e07000-44e07fff : 44e07000.gpio
44e09000-44e0afff : /ocp/serial@44e09000
44e09000-44e0afff : omap_uart
44e0b000-44e0bfff : /ocp/i2c@44e0b000
44e0b000-44e0bfff : /ocp/i2c@44e0b000
44e10620-44e10623 : 47400000.usb
44e10628-44e1062b : /ocp/usb@47400000
44e10800-44e10a37 : /pinmux@44e10800
44e10800-44e10a37 : pinctrl-single
...
Do you have any suggestions for how to clean up the kernel in this case?
Thanks,
Phil
